The imidazolidine derivatives were prepared via [1 + 1] condensation of various aldehydes such as 2-Hydroxy benzaldehyde, 2-fluoro benzaldehyde, 2-chloro benzaldehyde, pyridine-2-carbaldehyde, pyrrole-2-carbaldehyde, thiophene-2-carbaldehyde, furan-2-carbaldehyde with N,N′-bis((pyridine-2-yl)methyl)ethane-1,2-diamine (L) in the solvent of acetonitrile and characterized by the appropriate spectroscopic methods (FT-IR, UV–Vis, molar conductivity, 1 H and 13 C NMR, EI-Mass, X-ray). By coordinating the imidazolidine ring to the metal ions, this ring can be stabilized or hydrolyzed and converted to initial materials. Therefore, in this research, to investigate the effect of imidazolidine ring pressure and the effect of different groups in neutralizing this pressure in coordination with manganese(II) ion, the Manganese(II) complexes of these compounds were synthesized and characterized by FT-IR, UV–Vis spectroscopy, molar conductivity, EI-Mass spectrometry, and X-ray crystallography. The spectroscopic data for the imidazolidine derivatives confirm their formation. The manganese(II) complex of these compounds showed that the imidazolidine ring was unstable due to coordinated and created pressure on the imidazolidine ring and the presence of different groups on the ring does not affect the stability.
